Maintain a straight spine, sitting in Easy Pose or a chair.
Keep your head level, not tipped up or down.
Open the mouth and form an “O” shape with the lips. It may help to slightly pucker the lips.
Extend the tip of the tongue past the lips, and curl the tongue lengthwise into a straw shape.
Inhale slowly and deeply through the rolled tongue, filling the lungs completely (as in Long Deep Breathing).
Exhale slowly and fully through the nostrils.
